Error with urllib3 and the python-telegram-bot API

Question

when i try to run my script (my telegram bot) the following appears in terminal:

/usr/local/lib/python3.7/dist-packages/python_telegram_bot-12.4.2- 
py3.7.egg/telegram/utils/request.py:47: UserWarning: python-telegram-bot is using upstream urllib3. 
This is allowed but not supported by python-telegram-bot maintainers.

what I do?

Thanks a lot

Answer 1

Originally, python-telegram-bot only shipped with a vendored version of urllib3 that was created to fix a bug that could not be fixed upstream.

To allow python-telegram-bot to be shipped as part of Linux distributions, the dependency on the vendored urllib3 has been made optional, allowing python-telegram-bot to work with the standard urllib3.

So the message you're seeing is expected behavior if you installed python-telegram-bot through your distribution's packet manager. If your bot works fine, you don't have to change anything.
